There is freeware out there provided by the Minnesota Department of Natural Resources that allows Garmin users to download their data in a number of different format. Search "DNRGarmin GPS Application" and follow the instructions. This is great for GIS user because it will download to a shapefile.

It has the ability to upload some data, as well. Although, I suspect there are fewer options for uploading data than, say, Mapsource.

You will need to use the Mapsource program or something like EasyGPS, or ExpertGPS. You will tell the program to download all the data from your GPS when it is connected. It will download the waypoints, routes and tracks to your computer.

f a device is locking up and has a long noise or beep when powering
down, this is due to hidden data being transferred to the microSD data
card. These hidden files and folders are being created by the computer
and sent to the data card in addition to the maps, waypoints, routes,
tracks and pictures that were selected. The following GPS units could
experience this issue.

eTrex Legend Cx

eTrex Legend HCx

eTrex Venture Cx

eTrex Vista Cx

To
prevent this issue when the device is shutting down delete these extra
unused or hidden files and folders from the data card. Examples of these
folders are: .Trashes and .Spotlight-V100 folders. Since the Mac OS
adds hidden files and folders to mounted removable drive volumes this
process cannot be done on a Mac and will need to be done after every
time the data card is mounted as a volume on a Mac.To delete these folders the device will have to be placed into USB Mass Storage mode. To do this:

Connect the device to the computer using the USB cable

Go to the Main Menu

Select Setup

Select Interface

Select USB Mass Storage Mode

The
device is now in USB Mass Storage Mode. At this time a window should
open on the computer desktop displaying Removable Disk at the top. The
Garmin folder will be displayed. Open the Garmin folder.Do NOT delete the the following files:

gmapsupp.img

gmapsupp.unl

gmapsupp.gma

These files contain supplemental mapping. If delete will cause the mapping to be erased or unviewable.If
there are other folders or files on the data card, delete these. Some
of these files or folders may be hidden and therefore will need to be
unhidden*. Once you have done so, please disconnect the device from the
computer and power it up.*Note: To Display a file folder that is hidden:

Select the Tools option on the window that appears on the computer when the device is in USB Mass Storage Mode

Select Folder Options

Select View

Open the Files and Folders folder

Open the Hidden Files and Folders folder

Select Show hidden files and folder

Select Apply

Select OK

Once all of the hidden files and folders have been removed from the microSD Card the unit will not

There is no software for your etrex GPS to install on your computer. You can, however, purchase Garmin maps to install onto your GPS. When you purchase this mapping software, it will include a copy of Mapsource, which is used to upload and download tracks and waypoints to your unit.

You need to have Mapsource running, select the Topo USA 2008 maps to show on your screen. Use the Map Select tool, and select all the maps you want to send to the unit. Then hit the Send to GPS at the top and a pop up window asks what you want to send. Select Maps.

If this is what you have done already, please come back and tell us and we'll trouble shoot from there.

I have the same problem. The unit works until I connect it to whatever computer via USB (Mac or PC). The screen blanks out as soon as I plug in the USB cable. I have to disconnect the device and only then I am able to turn it on again. That started after Firmware update from V 2.90 to 3.00 . I am not sure this is causing problem. What about the firmware versions of your devices ? Are they all on the latest ?
However, does anybody know if there is a way to go back to firmware version 2.9 if it is not possible anymore to connect the device to any computer (evtl. through putting data on the microSD card ?).
Thanks,

Please translate this procedure. The important matter for you is that you now have mapsource active and with de Keygen v1.3, you can unlock a lots of maps. Please don´t publish this solution, because a lots of people would not have access in the future to this program.
